Whole Orange Cake Recipe

Our orange and almond cake is made using whole oranges (including the peel!). The oranges are boiled until soft and then pureed into a smooth paste. 

How To Boil Oranges

Step 1 – Cut the very ends off two oranges and place the oranges into a large saucepan or pot.

  • Cover the oranges with water and place a lid over the top
  • Bring to the boil and then reduce to a simmer for 2 hours or until the oranges are very soft and can be easily pricked through the skin with a fork
  • You will need to keep an eye on the oranges and top the water up a few times while they’re cooking

Step 2 – Take the oranges out of the saucepan and place onto a plate to cool. 

  • Roughly chop into small chunks (including the peel).

Step 3 – Place into a food processor, blender or Thermomix and blend until a smooth paste remains

Tips For Making Orange And Almond Cake

The Best Type Of Orange To Use

If possible, choose navel oranges which are seedless, juicy and bright in colour. If you can’t find seedless oranges, remove the seeds once the oranges have been boiled and chopped up. 

Almond Meal

You can buy packets of pre-made almond meal from the nuts section of any supermarket. Almond meal is the same as ground almonds – so you can always make your own almond meal by grounding whole almonds if you prefer. 

If The Cake Is Browning Too Much

If you notice that your cake is browning too much, simply place a sheet of foil loosely over the top and continue to cook. 

Using A Springform Tin

In this recipe we recommend using a greased and lined springform tin. This allows the dense cake to be easily removed after baking and doesn’t;t disturb the flaked almonds on top. If you don’t have a springform tin, you can use a well greased and lined cake tin (with the base and sides lined with baking paper) and very carefully remove the cake once it’s cooled. 

Storing And Serving The Cake

This cake can be kept in an airtight container at room temperature for up to 4 days or frozen for up to 2 months. Serve at room temperature or warmed up slightly (it’s delicious with whipped cream on the side too!).

    This is an awesome cake! Best flourless cake I have made. I whisked my egg whites which made it a lighter cake and it was an absolute winner at my work function that every one wants the recipe – not sure I want to share .
    I cooked some thin orange slices and put it on top and made some syrup with fresh orange juice and water and a little brown sugar and poured it over the cake.
